Western Colorado and eastern Utah have warmed in the last century, and it appears that precipitation in the region has also increased, according to a new analysis of historic climate data compiled by Grand Junction-based National Weather Service forecaster Joe Ramey. General long-term trends include cooling from the 1940s th

Efforts to curb global warming have quietly shifted as greenhouse gases inexorably rise. The conversation is no longer solely about how to save the planet by cutting carbon emissions. It's becoming more about how to save ourselves from the warming planet's wild weather.

Analysis has suggested that changes in the atmosphere will lead to more frequent conditions favorable for severe thunderstorms. According to recent studies there will be more damaging winds related to thunderstorms. The number of tornadoes and large hail is expected to remain at the same level as today.

 If the climate continues to evolve as predicted by the Intergovernmental Panel on Climate Change, the United States stands little to no chance of satisfying its current biofuel goals, according to a new study by Rice University and the University of California at Davis.

Southern California's water needs are met primarily by snow falling and water flowing from distant mountains. From the rugged eastern side of the Sierra comes the Owens River, which the city of Los Angeles tapped not just once — with William Mulholland's century-old aqueduct — but repeatedly with extending and parallel arteries.

The seven basin states of the Colorado River are being hammered with drought and diminished snowpack that will create the lowest levels at Lake Powell and Lake Mead in 45 years.

Nolan Doesken used to have a hard time talking about climate change. The topic has become so politically combustible that some scientists and researchers find it difficult to speak of or write about. But, after the High Park Fire swept the foothills in 2012, Doesken decided to talk more openly about the reasons behind Colorado’s changing weather when talking to the agriculture community.

Long-time skiers often say that skiing was better in the good old days, and new research from the U.S. Geological Survey suggests that those claims are based on more than nostalgia — notwithstanding the occasional bumper crop of powder like in 2010-2011.

The old saying that "what goes up must come down" doesn't apply to carbon dioxide pollution in the air, which just hit an unnerving milestone. The chief greenhouse gas was measured Thursday at 400 parts per million in Hawaii, a monitoring site that sets the world's benchmark. It's a symbolic mark that scientists and environmentalists have been anticipating for years.
